Recommendation Device Using Location Verification for Reliability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The reliability of recommendation information provided by map information providing servers is low due to self-reported attribute information from information providers, which reduces the accuracy of recommendations.

Innovation Solution

A recommendation information providing device that communicates with both provider and requester terminals, acquires and stores location information, and transmits relevant recommendation information based on search area data to enhance the reliability of attribute information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If attribute information is registered by information providers themselves, then the system is simple and easy to operate, but the reliability of the attribute information becomes low

Engineering Contradiction:

Improveease of registrationVSAvoidreliability of attribute information

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a map information providing server as an intermediary that collects location information from multiple information providers and uses it to verify and enhance the reliability of self-reported attribute information. The server acts as a neutral mediator that aggregates objective location data to validate subjective provider information.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by using collected location information to verify and improve the reliability of attribute information. The map information providing server continuously receives location updates and uses this feedback to assess and validate the accuracy of information provider registrations.

Inventive Principle:

Principle #23Feedback

2Device complexity

If fixed registered locations are used, then the system structure is simple, but the accuracy of recommendation information decreases when providers move

Engineering Contradiction:

Improvesystem structureVSAvoidaccuracy of recommendation information

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent transitions from static registered locations to dynamic location tracking by continuously collecting current location information from information providers' mobile terminals. This allows the system to adapt to provider movements while maintaining recommendation accuracy without significantly increasing system complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary location information collection and storage before recommendation requests are made. By pre-collecting and storing location data from multiple providers, the system is ready to quickly and accurately respond to recommendation requests without real-time calculation delays.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If self-reported user information is stored, then data collection is easy, but the reliability of recommendation information is reduced

Engineering Contradiction:

Improveease of data collectionVSAvoidreliability of recommendation information

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent merges self-reported attribute information with objectively collected location information from mobile terminals. By combining these two data sources, the system maintains the ease of data collection while significantly improving reliability through the verification provided by independent location data.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The map information providing server serves as an intermediary that collects and verifies location information independently of user self-reporting. This intermediary validation layer enhances the reliability of recommendation information while maintaining the simplicity of self-registration.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A recommendation information providing device that communicates with each of a mobile terminal used by a provider of recommendation information and a requester terminal used by a requester of the recommendation information includes: acquisition means for acquiring location information of the mobile terminal; memory means for storing the acquired location information; storage means for storing the recommendation information of the provider; and control means for, when receiving search area information for identifying a search area from the requester terminal, identifying a pertinent terminal which is the mobile terminal existing in the search area with reference to the memory means and transmitting pertinent recommendation information which is the recommendation information of the provider using the pertinent terminal to the requester terminal with reference to the storage means.
